To be honest, Zack's question is spot on when looking for a co-founder; especially when all you're giving back in return is equity.

Who are you? What have you done in the past? Can you show the community what you've done so far? I think the legal trouble you mention also needs some explanation (assuming you can talk about it in this open of a forum). A little effort can go a long way here.

You don't know Zack, but he runs a kickass online music service, bootstrapped by himself and he built everything.

To be fair, at the very least Zack has links in his profile and >2000 karma on HN. Yours is a brand new account with no bio.
